Hi! Does anyone have a ressource to explain how Lemmy works in terms of the more complicated stuff, as:

  • If a community is hosted on instance A and a user that’s on instance B creates a post in this community, is the post hosted on A, B? Or are individual comments hosted on the instance of their respective authors?
  • what happens when your account gets deleted? Are all my messages deleted? Does this happen to all instances (it syncs the deletion?)
  • do instances cache posts and comments posted on other instances? If so, RAM or disk?
  • will having too many instances increase the load of all instances? (If they all have to sync?)
  • if I want to check the comments of a post, does my client ask this to my instance of to the instance of the author or to the community’s instance?

Questions like this. I guess most will be answered by explaining deeply how ActivityPub works but if anyone has that info, please share :)

    Banned on local instances, is the same as being deleted. Banned by another instance means you won’t show up on that instance.

    Atop all this there’s defederation.

    My instance for example won’t count votes or show comments from users with accounts on lemmynsfw, because we defederate porn. This happens even if I go look at posts in a community on another instance that does federate with lemmynsfw.
